IMPROVEMENT IN NIACHIES FOR PLASTERING.

Specification forming part of Letters Patent No. 10,590, dated March '7,1854.

To all whom it may concern.-

Beit known that I, IsAAo HUssEY, of Harveysburg, in the county of Warrenand State of Ohio, have invented a new and useful Machine forPlasteringY Overhead, Side Valls, dac.; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure l is an isornetrical perspective view ofthe machine as it appears when plastering overhead. Fig. 2 is a verticaltransverse section of the mortar-box, trowel, and follower separate fromthe machine, the rails for preventing the mortar-box from scratchingafter the irst and second coats have been put on being also shown.

The saine letters of reference in each of the several figures indicatecorresponding parts.

The nature of my invention consists in plastering the outer and side andalso the top walls of buildings by means of a machine constructedsubstantially as herein described, the said machine having an adjustablemortar-box and also a trowel, which arc adjustable to any height andposition necessary, and it being also set on rollers, so that it may bepropelled across the room very easily, and a portion of the said machinebeing adjustable to suit different heights of walls.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A represents the main frame of the machine, which may be of the formrepresented or of any one more suitable. upon which it rests and ispropelled across the room or from one position to another.

C is an adjustable pulley-frame, which is so arranged as to move up anddown in slots or mortises cut in cross-pieces of the main frame, asshown in Fig. 1. This frame, as before stated, carries pulleys, two ormore, (lettered D 1),) over which the elevating-cord E passes from thedrum F, arranged and turning on the front top cross-piece of the frameA, to the mortar-box G, arranged on the back portion of the machine andsliding up and down the guide-rails a of, of the movable frame H, thesaid frame being made to slide horizontally back and forth by means ofthe lever I, which is made to serve two purposes, that of B B are therollersl keeping the mortar-box G against the side of the wall when theoperation 'of plastering side walls is being carried on and that ofoperating the piston J, which operates the follower or mortar-feeder Kofthe box G, when plastering overhead. l

The arrangement of the pulley-frame and c also the fral'newhich carriesthe mortar-box and operates upon it will be clearly seen by examiningthe drawings. The mortar-box G is attached to a cross sliding piece b,which has two triangular-shaped lgrooves c c cut in its ends, in whichthe triangular-shaped edges of the guide-rails c a fit loosely so astoallow of the mortar-box being raised and lowered by the saidcross-piece being moved up and down along the guide-rails o a when themachine is in operation. This mortar-box has a trowel L, which isarranged on the top and near the back end of kthe box, it being securedloosely in two movable bars d d, which slide in grooves ce cnt in eachend of the box G. These bars are for setting the trowel L either out orin, so as to put von coats of different thicknesses. This trowel has themortar fed to it by the follower K, which is'operated by the pistonattached to the lever I, and by means of a spring, cord, and weight, orother device, which will draw the follower back for a fresh supply ofmortar.

M is a slide working in grooves ff in the sides of the box G, the saidslide serving to close the throat of the box, and thereby cut themort-ar oft from the trowel. This slide is worked by a lever O, attachedto the follower K, in the manner shown in Fig. 2. To this lever a cord g(shown in red) is attached and then carried over to the operator, who bypulling it can, operate the slide and close the throat of the box. InFig. 2 the box is shown as operating overhead, it being full of mortarand the trowel set out far enough for putting on the first coat.

The cord which draws the box up along the side and to the top of thewall is made to wind in the groove h of the drum F, thev said drum beingset in motion by the endless chain N, which is operated in any suitableway.

The different operations of the machine are as follows: In plasteringoverhead the box is filled With mortar through the opening in the top ofthe box, after which the opening is closed by a slide and the box isthen run up to the top of the machine by operating the endless chain N,and thereby the cord attached to the mortar-box, and Winding it upon thedrum. After this the machine must be moved from one side of the room tothe other and t-he mortar fed to the trowel by the follower, which isoperated by the piston and lever, which operation plasters one-half ofthe overhead Wall, then commencing at the other side and iinishing up tothe center, thus putting on the Whole of the first coat, after Which thetrowel must be properly set, either in o r out, as may be necessary, soas to put on the second and third coats. Thus the top Walls areplastered. In plastering side Walls the part of the box which playedagainst the top Wall is turned down so as to run against the laths onthe side of the Wall and the mortar is forced against the side of theWall in any suitable Way, the box being held to the Wall by action ofthe guide-rails or movable sliding frame II, the said frame and railsbeing pushed toward it by the lever I, which is disconnected in thiscase from the piston and connected to the sliding frame H by the straps, the lever being moved back and forth, as desired. The box after beingfilled with m0r tar is run up and down alongside the Wall by the endlesschain, duc., and thereby the plaster is put on. After the first coat hasbeen put on it is necessary to employ an extra set of rails t, so thatin putting on the second coat and skin coats the mortar-box can beoperated Without scratching the plastering and also prevent the mortarspewing out. These rails must be attached to the guide-rails when `usedfor this purpose. The troWel must, when lthese rails are used, be setout very near to the edge of the box.

'Vhat I claim as my invention, and desire to secure by Letters Patent,is-

The arrangement of the several parts of the machine, substantially asand for the purpose herein described.
